Specification of Letters Patent. Patented July 27, 192() Application filed December 30,1919. Serial No. 348,359.

To all whom it'mag concern:

Be it known that I, DANIEL MEnoInR, a citizen of the Republic of France, residing at 4: Place St. Francois, Annonay, Ardeche, in the Republic of France, have-invented new and useful Improvements in Machines for Treating Hides and Skins, of which the following is a specification.

This invention relates to improvements in machines for treating hides and skins such as putting out, dcpilating, stretching and similar'machines. According to the invention, the hide is brought to the working cylinder by a sliding supporting cylinder operated by means of an improved construc tion of link mechanism.

The'invention consists also in providing a micrometric device whereby the distance between the working cylinder and the supporting cylinder in operation correspond ing to the thickness of the treated skin, may Y be accurately measured.

In the annexed drawings, given by way of example:

Figure 1 is a side view of the hide working machine constructed in accordance with the invention. 1

Fig. 2 is a vertical section, along the line XX Fig. 3, of the micrometric device.

Fig. 3 is a side view and Fig. 4 is a plan view of the same.

' On the frame A of the machine, is mounted a working cylinder O which rotates in the direction shown by the arrow under the action of any suitable driving mechanism not shown. The cylinder O is provided on its periphery with blades having a suitable shape according to the special treatment to be effected on the skin. At theopposite ends of the frame are mounted two inclined slideways G in which slides H may be displaced, said slides carrying the shaft 10 of a supporting cylinder D. The frame is also provided with guides 11 for the shaft 12 of a pressing roller E, the shaft 12 being yield- 7 ingly maintained in its lower position by springs R.

Provided on the outer side of one of the slideways G, at a normally fixed point, is a stud shaft F upon which a link 6 is freely pivoted. The position of'the stud shaft F along the axis line Y-Y of the slideway may be adjusted by means of a device of a known construction embodying a screw and a rubber buffer not shown on the drawing. On the corresponding slide H is mounted a stud shaft 9 upon which is journaled a link 0 forming with the link Z) a toggle mechanism, the free ends of the links 6 and 0 being both pivoted-at 13-to the driving connecting rod B. The latter is connected at its lower end. to a lever arm M secured on a shaft 14 carried by theframe of the machine. On the shaft 14 is keyed an arm 15 carrying at its free end a spring mounted roller 16 operated bya cam N carried on a shaft 17 which isrotated by the driving mechanism of the machine. On the shaft 14-, is also secured an arm 18provided with a pin 19 which may be lowered by an arm 20 secured on a shaft 21. On said shaft is also secured a foot lever LL When the-cam N rotates or when the foot lever L is depressed, the connecting rod B is raised-and the toggle opens whereby the slide H is moved upwardly in the-guideways G. The hide WV to be treated is placed over the supporting cylinder D so that when the slide H moves upwardly, the cylinder '1) is brought to the operative position shown at D and the skin is thereby subjected to the action of the working blades on the cylinder C. It is pressed at the same time between cylinders C and E and thereby ejected from the machine. I v

According to the invention, the'link 0 and connecting rod B, are so arranged that when the slide H occupies its lower or inoperative position as shown in Fig.1, said link 0 is substantially in alinement with the main connecting rod B. By means of said arrangement, the connecting rod B, when raised by the arm M acts in a very' efficient manner onthe link 0 for moving the slide l-l ipwarclly. The operation would obviously be much less satisfactory if, as in known constructions, the main connecting rod B were in substantial alinement with the bisectriX Z-Z of the angle between the links 6 and 0, since in that case a consider able amount of power'would be lost against the stationary member upon which the stud Y frame.

increased whereby the slide may be moved to a much lower point and the supporting cylinder D may be moved much farther away from the working cylinder C. By.

these means, a much greater space is left free for placing the hide over the cylinder D which is highly advantageous especially in the case when the hides to be worked upon have large dimensions.

The invention comprises also amicrometric devicewhereby the space between the supporting cylinder D,when it occupies its working position, and the blade carrying cylinder C may be accurately measured. One such micrometric device is provided at each end of the machine, respectively, The rear end of each slide H is formed by an abutment plate 24.- through which a threaded spindle may extend freely, said spindle K being screwed through the end part G of the The upper end of the spindle or screw K is provided with a head 0 by which the abutment plate 24: on the slide H is arrested when the slides H and the supporting cylinder D carried by the same reach the upper end of their stroke. The abutment screw K is rotated in the part G ofthe frame by means of a horizontal trans verse shaft 1 journaled on the machine frame and carrying an operating hand wheel U. A worm on said shaft meshes with a helical wheel 2 keyed on the same shaft as a lengthened pinion 3 in engagement with a toothed wheel t keyed on the outer end of the adjusting screw K. ,The worm 1- operates also through the medium of a gearing 5, two shafts S, T provided with pointers moving over suitable dials S T, The

dial S reads for instance in one hundredths of amillimeter and the dial T in millimeters. The micrometric device is inclosed in a casing 25 secured on the machine frame and provided with a lid 26which ishinged at and may be opened for disengaging the indicating gears 5 from each other and permitting to reset the apparatus to zero very rapidly for instance after repairs to the working cylinder C or supporting cylinder D. One micrometric device suchas that above described is provided for each of both screws K so that by rotating the handwheels U the cylinder D may be adjusted in accurate parallelism with the working cylinder C and also the thickness to be given to the hide acted upon may be accurately adjusted, the dials S T of the indicating mechanism allowing of precise measurements. 7

Havingnow described my invention, what ,I' claim as new and desire to secure by Letters Patent is:

l. A machine for treating hides and skins comprising a working cylinder, a supporting cylinder for the work, a carrying memher for said supporting cylinder, means for imparting to saio carrying member a re ciprocating movement in an inclined direction, said means embodying a toggle mechanism formed of a link pivoting about a fixed point and a link connected to the said carrying member, a connecting rod and means for operating the cylinders and connecting rod, the arrangement being such that when the carrying member is in its lowest position,

the link connected to the carrying'member and the connecting rod are substantially in alinement with each other. i

2. A machine for treating hides and skins ing cylinder for the work, means for driving said cylinders, slides in which the ends of the supporting cylinder are respectively journaled, inclined slideways for said slides, means for imparting to said slides a reciprocating movement, abutments for limiting the upward stroke of the slides and screw connections for adjusting the position of said abutments.

comprising a working cylinder, a support- 3. A machine for treating hides and skins 1 gears connecting each of the worms to the corresponding set of indicating means.

In testimony whereof I have signed my name to this specification in the presence of 'two subscribing witnesses.
